Frequently Asked Questions
Alloy steels are steels alloyed with elements such as chromium, nickel, molybdenum, or vanadium to improve mechanical properties and performance.
Alloy steels are used in aerospace structures, pressure vessels, pipelines, tools, and machinery requiring high strength and toughness.
Alloy steel differs from carbon steel by the addition of alloying elements like chromium, nickel, and molybdenum to improve mechanical properties and corrosion resistance.
Types include low-alloy steel (up to 8% alloying elements) and high-alloy steel (above 8%), tailored for strength, wear resistance, or toughness.
Commonly added elements include chromium, nickel, molybdenum, vanadium, manganese, silicon, and boron to enhance strength, hardness, and corrosion resistance.
